CHAPTER 2
When the lift-up cam is unfixed, the lift-up arm lifts up the lifter gear one tooth by the
rotation of the lift-up cam. The paper lifting plate is lifted up by repeating the operation.
(See Figure 2-2-9)
When the paper on the paper lifting plate touches the pick-up roller, the pick-up roller shaft
is lifted up. Then, the fixing arm is released, and the lift-up release arm lifts up the pick-
up roller shaft to the waiting position by force of the spring. At the same time, the pick-up
roller shaft fixing arm and the lift up release arm are driven to fix the lift up cam. As a
result, the lift up arm is stopped and lift up operation is competed.
